Hey, I am planning on purchasing an Audi A4 2009 1.8t. I am pretty much new to this customisation game. One thing I want to do to the car is modify the exhaust or purchase an exhaust system however as I was browsing online all I could find were exhaust systems for the 2L version of the car. Would the 2L version still be compatible with the 1,8L? Also what are some good exhaust systems that you would recommend or any other modifications I can do to make the exhaust sound good. Thanks
